tegra: i2c: re-init i2c controller after reset

This serves as supplemental patch to CL:197732. After clearing bus, we
    should also redo controller init (because controller has been reset
    before bus clear). On the upper layer, upon receiving error return status,
    it should just retry instead of simply call cpu_reset().
